Synthacon VCF

[Jim Patchell]

    Thanks for the link, Ian....You never know where you are going to find
something.

    And I would also like to say "your welcome" to all those who have thanked me
for posting the various articles I have scanned.  However, they won't be there
for long.  Anybody who wishes to download them and post them someplace else is
more than welcome to do so.  I have to pay for my hard disk usage over 5 Meg (I
am up to about 14 right now), so, I am trying to keep my usage down as much as
posible.
